Candlestick patterns & Bollinger Band

  A request that was addressed to ProRealTime:

   

  Dear ProRealTime programmers.

  I would like a Screener that identifies 4 different candlestick patterns with an upper or lower bollinger band breakout.

  These are the four candlestick patterns that the screener should be able to identify: Bearish Engulfing, Bullish Engulfing, Dark Cloud Cover and Piercing Line.
  For the bearish engulfing and the Dark Cloud Cover the end price of the first candle has to be higher than the upper band level. The start price of the second candle got to be higher than the upper bollinger band as well.
  For bullish engulfing and piercing line it is the opposite, first candle close price is below the lower band and the start price of second candle is below the lower band.

  The settings for the Bollinger should be as default:
  MA nbr periods: 20
  Standard deviation: 2
  Method: Simple
  Apply to: Close

  It got to work on both the deaily, weekly and monthly timeframe.

  If there is some additional info that is necessary for the coding, please let me know.
  Awaiting your response with anticipiation!
  Regards

  Suggestion for an anwser:

  Here below you can find the code that you can launch in daily or weekly timeframes. (Please note that the timeframe monthly does not exist in ProScreener):

  //bollinger P=20 //period S=2 // Standard deviation BollingerMA = Average[p](close) STDDEV=STD[P](close) bollUP = BollingerMA + s * STDDEV bollDOWN = BollingerMA - s * STDDEV // Detection bearish engulfing bearishengulfing = CLOSE[1] > OPEN[1] AND OPEN > CLOSE[1] AND CLOSE < OPEN[1] // Detection bullish engulfing BullishEngulfing= CLOSE[1] < OPEN[1] AND OPEN < CLOSE[1] AND CLOSE > OPEN[1] // Detection dark cloud cover (bearish reversal) darkcloudcover = CLOSE[1] < OPEN[1] AND OPEN < CLOSE[1] AND CLOSE > OPEN[1] // Detection piercing piercing = CLOSE[1]<OPEN[1] AND OPEN< CLOSE[1] AND CLOSE>(CLOSE[1]+(OPEN[1]-CLOSE[1])/2) AND CLOSE < OPEN[1] priceoverupperband=close[1] > bollUP and open > BollUP priceunderlowerband=close[1] < bollDOWN and open < bollDOWN condition=((bearishengulfing or darkcloudcover) and priceoverupperband) or ((BullishEngulfing or piercing) and priceunderlowerband) screener[condition]

  //bollinger P=20 //period S=2 // Standard deviation   BollingerMA = Average[p](close) STDDEV=STD[P](close)   bollUP = BollingerMA + s * STDDEV bollDOWN = BollingerMA - s * STDDEV   // Detection bearish engulfing bearishengulfing = CLOSE[1] > OPEN[1] AND OPEN > CLOSE[1] AND CLOSE < OPEN[1]   // Detection bullish engulfing BullishEngulfing= CLOSE[1] < OPEN[1] AND OPEN < CLOSE[1] AND CLOSE > OPEN[1]   // Detection dark cloud cover (bearish reversal) darkcloudcover = CLOSE[1] < OPEN[1] AND OPEN < CLOSE[1] AND CLOSE > OPEN[1]   // Detection piercing piercing = CLOSE[1]<OPEN[1] AND OPEN< CLOSE[1] AND CLOSE>(CLOSE[1]+(OPEN[1]-CLOSE[1])/2) AND CLOSE < OPEN[1]     priceoverupperband=close[1] > bollUP and open > BollUP priceunderlowerband=close[1] < bollDOWN and open < bollDOWN   condition=((bearishengulfing or darkcloudcover) and priceoverupperband) or ((BullishEngulfing or piercing) and priceunderlowerband)   screener[condition]
